构造方法数据类型的测试

9.1新建一个Demo1的实体类

packagecom.eduask.entity2;

//新建一个Demo1的实体类;

publicclassDemo1 {

privateintid;

privateString name;

privateString pwd;

publicDemo1() {

}

publicintgetId() {

returnid;

}

publicvoidsetId(intid) {

this.id = id;

}

publicString getName() {

returnname;

}

publicvoidsetName(String name) {

this.name = name;

}

publicString getPwd() {

returnpwd;

}

publicvoidsetPwd(String pwd) {

this.pwd = pwd;

}

@Override

publicString toString() {

return"Demo1 [id=" + id + ", name=" + name + ", pwd=" + pwd + "]";

}

publicDemo1(intid, String name, String pwd) {

super();

this.id = id;

this.name = name;

this.pwd = pwd;

}

}

9.2 新建一个TestDemo1的测试类

packagecom.eduask.entity2;

importorg.springframework.context.support.ClassPathXmlApplicationContext;

publicclassTestDemo1 {

publicstaticvoidmain(String[] args) {

ClassPathXmlApplicationContext cx=newClassPathXmlApplicationContext("entity2Xml/demo1.xml");

Demo1 demo1=(Demo1) cx.getBean("Demo1");

System.out.println("构造方法类型的测试");

System.out.println(demo1);

}

}

9.3新建一个Demo1.xml的配置文件

<?xml version="1.0"encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans.xsd"

>

<bean id="Demo1"class="com.eduask.entity2.Demo1">

<constructor-arg name="id"value="001"index="0"type="int"/>

<constructor-arg name="name"value="tom"index="1"type="String"/>

<constructor-arg name="pwd"value="123456"index="2"type="String"/>

</bean>

</beans>

9.4程序运行如下:

构造方法类型的测试
Demo1 [id=1, name=tom, pwd=123456]
